I can describe the parts of a neuron cell and identify how they transmit electrochemical impulses.. The . function of the nervous system is:. To sense, interpret, and respond to internal and external environmental changes to maintain a steady state in the . body (homeostasis). The nervous system is divided into two major structures: . The Nervous System: Communication. Neurons are masses of nerve cells that transmit information. Three main components:. (1) Cell Body – contains the nucleus and two extensions. (2) Dendrites – shorter, more numerous, receive information. The Nervous System Central Nervous System Peripheral Nervous System Procedure A starting person will be chosen and will be given an object. Once the teacher gives the signal, the start person will pass the object to their right. 1. Two main divisions. a. . Central Nervous System . (CNS) – consists of brain and spinal cord. b. . Peripheral Nervous System . (PNS) – includes nerves extending from . brain and . spinal . cord . 17.4 The Peripheral Nervous System. The peripheral nervous system is composed of nerves and ganglia. . Nerves . are bundles of axons. . Ganglia . are collections of cell bodies. . The peripheral nervous system is subdivided into the somatic system and the autonomic system. . Ms. Sallo. AP . Psychology. March 8, 2016. Peripheral Nervous System (PNS). Def: made up of all those nerves that lie outside the brain and spinal cord. . Nerves are bundles of axons that are routed together in the PNS. (CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves. N Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and 1 2 CSFFormed at choroid plexuses in the ventriclesCushioning effectNormal: 10 mmHg in pressure, 1.002 1.009 in SG, 7.32 in pHncreased productiondecreased absorption, and/orobstruction of flow ofCSF a Divisions of the Nervous System.
